Wilson Towers as Local Bulk Fields
Vishal Gayari, Chethan Krishnan
Multi-winding Wilson loops (``Wilson spools'') in 2+1-dimensional gravity can reproduce one-loop partition functions of local free fields in the bulk. Bulk free fields have a secon…
Holography, Brick Wall and a Little Hierarchy Problem
Vishal Gayari, Chethan Krishnan, Pradipta S. Pathak
We propose a heuristic for the brick wall in AdS/CFT: the location where a boundary mode's local bulk energy reaches a (Planckian) UV cut-off. This accomplishes two things: (a) the…
Geodesics from Quantum Field Theory: A Case Study in AdS
Vaibhav Burman, Chethan Krishnan, Livesh Parajuli
Localized one-particle states of a quantum field theory--whether in flat space or on a curved background--are expected to exhibit geodesic motion in an appropriate semiclassical re…
Holography with an Inner Boundary: A Smooth Horizon as a Sum over Horizonless States
Chethan Krishnan, Pradipta S. Pathak
The (holomorphic) partition function of the Euclidean BTZ black hole with boundary modulus , is the -image of the Virasoro vacuum character, . This obje…
Virasoro Blocks and Trouble at the Euclidean Horizon
Aaditya Datar, Chethan Krishnan
In the semi-classical () limit, 4-point HLLH correlators in 2D CFTs exhibit periodic Euclidean singularities. Periodic singularities in Euclidean time are a g…
An Analytic Zeta Function Ramp at the Black Hole Thouless Time
Pallab Basu, Suman Das, Chethan Krishnan
Black hole normal modes have intriguing connections to logarithmic spectra, and the spectral form factor (SFF) of is the mod square of the Riemann zeta function (RZF…
